Description
Technical field
The present invention relates to a kind of technical field of composite materials, it is that a kind of carbon fiber removes slurry, quetsch, is used for same carbon
Under the conditions of fiber, the evaluation and test of different sizing agents and starching amount, and in particular to a kind of carbon fiber sizing agent evaluating apparatus and evaluation and test side
Method.
Background technique
Carbon fiber is a kind of fibrous material for the excellent combination property that carbon element content is up to 90% or more.Carbon fiber
Preparation is the process that organic fiber is carbonized under certain condition, by carbon containing organic compound in atmosphere of inert gases
It is heated, when temperature is increased to several thousand degrees celsius, non-carbon element will be ejected out organic matter and disappear, and have in this way
Carbon element content in machine object will be gradually increased and ultimately form carbon fiber, and carbon fiber possesses fine and close connected atomic structure of carbon.
Carbon fiber is due to intensity is high, modulus is big, corrosion resistance is strong, endurance degree height, the small, high temperature resistant of specific gravity etc. are better than other fibres
The speciality of class reinforcing material is tieed up, and is widely used in the various fields in production and living.
The carbon of high-content determines the big feature of its surface inertness in carbon fiber, therefore is combined with matrix resin infiltration
Property it is poor, therefore be surface-treated in production and improve the surface-active of fiber.And carbon fiber is similar with quartz fibre,
It enbrittles big feature, fracture and the hair that fiber is easy to happen when the effect of power such as is stretched, rubs in process of production
The phenomenon that silk amount increases leads to the reduction of carbon fiber integral strength, and influences the progress of the subsequent bunchy of carbon fiber and knitting process, and
And resin can be made to be difficult to complete wetting carbon fiber in the presence of composite molding stage lousiness, inevitably in composite wood
Material is internal to form some lesser holes, and when use can collect moisture and then occur under the influence of the control ambient temperature of temperature
Condensation generates steam, can seriously damage the structure of composite material, greatly the mechanical property of weakening composite material and resistance to old
The property changed.In addition, working environment may also due to lousiness presence and wreck, endanger the health of staff.Therefore,
Sizing process becomes important procedure indispensable in carbon fiber production.
Starching is conducive to for carbon fiber bonding being bundled up, mention like a thin layer of protective clothing has been worn to carbon fiber
The high integral strength with when resin compounded, and carbon fiber can be effectively reduced, fracture occurs and the probability of lousiness occurs.According to phase
Like compatibility principle, matrix resin is often identical with matrix resin in carbon fiber sizing agent, and the carbon fiber after starching is easy
It is sufficiently infiltrated by matrix resin, to form good transition interface region between carbon fiber and resin matrix, increases carbon fiber
The comprehensive performance of strong composite material is played to greatest extent.Currently, for the fibre reinforced for meeting various use demands
The research of body and resin matrix is very complete, but the indices of the composite material actually prepared are much smaller than theoretical water
Flat, the destructions such as fracture are frequently experienced at composite material interface.Therefore, to the research of composite material interface for excavating it
Implicit great potential is of great significance.
The interface of fibre reinforced composites is in the transitional region that fiber is contacted with resin, plays transmitting between
The ties bridge beam action such as load, interface cohesion effect directly affect the performance of composite material overall efficiency.Interface cohesion effect
It is more excellent, more facilitate load and pass to the carbon fiber reinforcement of high-strength and high-modulus via interface, so that it is expected to play composite material
Performance indexes.Similarly, the sizing agent coating in carbon fiber with basal body interface region is compound for fibre reinforced
The performance of material comprehensive performance plays a very important role.
According to the research both at home and abroad in terms of carbon fiber starching, the reason of comprehensive carbon fiber starching, summarize on carbon fiber
The main purpose of slurry has the following aspects：
One, have the function of boundling, be similar to adhesive, carbon fiber is made to flock together, improves processing performance, it is easy to process；
Two, it is similar to coupling agent, boundary layer appropriate is introduced between carbon fiber and matrix resin, is promoted between fiber and resin
Chemical bonding, long lasting bond improve the interface performance of composite material；
Three, play the role of lubricant, i.e. sizing agent forms serous coat in carbon fiber surface, protects carbon fiber, reduces fiber and fibre
Friction between dimension, fiber and parts, reduces the generation of lousiness, keeps the mechanical performance of carbon fiber, improves wear-resisting property, keeps
Its intensity and machinability；
Four, play the role of completely cutting off air, fiber carbon fiber will enhance its surface-active by surface treatment before starching, but
Be enhanced active surface be easy absorption air in dust and moisture, serous coat can effectively make active surface and air every
Absolutely, fiber surface activity is kept；
Five, fiber reinforced effect, this distribution of carbon mono-filaments rheobase takes Weibull statistical distribution, and starching can be certain
The defect of fiber surface is made up in degree, so that carbon fiber strength before starching compared with increasing, the dispersibility of Weibull distribution subtracts
It is small, play certain reinforcing effect.
Finally, being equivalent to wetting agent, improve the wetting property of carbon fiber, is impregnated convenient for resin, reduce the system of composite material
The standby time, improve product quality.
Therefore, carbon fiber sizing agent is most important to carbon fiber production application, and evaluating a sizing agent the best way is
Comprehensive performance is revalued after in starching to specified carbon fiber.But in fiber actual production process, carbon fiber starching is influenced
Factor is more, such as polymerization, spinning, pre-oxidation, carbonization, surface treatment, drying, is the shadow for excluding these factors as far as possible
It rings, the present apparatus is first gone to starch using same ingot carbon fiber, then starching experiment, and then evaluates and tests the starching effect of different sizing agents
Fruit can also evaluate influence of the starching amount to carbon fiber by controlling starching amount.
Therefore solve the problems, such as that this kind is particularly important, this technology is paid attention in carbon fiber sizing process
And it solves the problems, such as.
